CURTAIN-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 481,978, dated September 6, 1892.

Application filed January 27, 1892. Serial No. 419,447. (No model.)

To all whom it may concern.:

Be it known that I, SAMUEL I-I. SNAVELY, a citizen of the United States, residing at Washington city, District of Columbia, have invented certain new and useful Improvements in Curtain-Fixtures; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, whereinw 1o Figure lis an elevation of a portion of a window, showing the fixtures and manner of attaching the same to the window. Fig. 2 is a transverse section on the line of Fig. l, illustrating the construction of the brackets,

whereby the same are adapted for use with frames of dierent depths and curtains which are wider than the sash. Fig. 3 is a detached perspective view of the bracket, showing the construction whereby the arm of the bracket 2o is rendered capable of adjustment to compensate for any irregularity in the height of the bracket shoe or socket. Fig. 4c is a face view of the outer section of the bracket. Fig. 5 is a back view of said outer section. Fig. 6 is a 2 5 face view of the inner section of the bracket or that next to the shoe or socket piece. Fig. 7 is a perspective view of the bracket shoe or socket piece. Fig. 8 is a view of a modification or short-section bracket adapted for use 3o in hanging curtains on windows having inside blinds.

Like symbols refer to like parts wherever they occur.

My invention relates to the construction of 3 5 brackets for curtain-fixtures, and has for its objects the production of a bracket which shall be adapted to meet the requirements of window-frames of dierent depths, to compensate for any inequality in the height of 4o b1'acket-supports, and applicable to windows having either outside or inside blinds.

To this end the main feature of my invention embraces a sectional extensible bracket having means for adjusting and securing the sections so that their longitudinal axes shall intersect,whereby the outer end of the bracket may be set either above or below the inner end thereof.

There are other minor features of inven- 5o tion,all as will hereinafter more fully appear.

The bracket hereinafter described may be applied either to the sash or the frame of a window; but has been especially devised for the upper sash thereof, so that said sash may be lowered to ventilate the rooms without rendering the curtain liable to be whipped out by the incoming air-current or to obstruct the entrance thereof.

I will now proceed to describe my invention so that others skilled in the art to which it 6o appertains may apply the same.

In the drawings, A indicates the windowframe, B the upper, and C the lower sash thereof.

1 indicates a bracket shoe or socket pro- 65 vided with a suitable open slot 2 for the reception of a dovetailed projection on the end of the inner section of the bracket. In casting the dovetailed projection on the inner bracket-section it is necessary to form an in- 7o eline on the end of said section, as at a', to facilitate the drawing of said casting, and to compensate for this and insure that the bracket shall stand at right angles to the sash I preferably form the bracket-shoe thicker at the heel, as at a, Fig. 7, so as to give said shoe a Wedge form or inclined face. The shoe l may be secured to either the frame or sash in any suitable manner.

3 indicates the extensible bracket, of which 8o 3a is the inner or shoe section, and is provided with a dovetailed projection 4, adapted to enter the slot 2 in the shoe l, and 3b is the outer or curtain section, which in the case of the curtains wider than the window-sash will have an elbow, as especially indicated in Figs. 2 and 3. In case the bracket is desired for use with curtains of less width than the sash (or for use with windows having inside blinds) the curtain-sections 3b will be propor- 9o tionately shortened and the elbow will be formed on the shoe-section 3a, as indicated in Fig. S of the drawings.

In order to arrange the bracket-sections 3a 3b with their longitudinal axes intersecting 95 or said sections at an angle to each other, so as to elevate or depress either or both rollerbearings when desired for ypurposes of adjustment, I form one of the contacting faces of one section with longitudinal grooves 5 Ioo and the other at or near its end with projecting points or teeth (3, adapted to enter the grooves 5.

In the drawings I have shown both of the contacting faces of bracket-sections 3 3b provided with said grooves 5 and points 6, as that is the preferred form; but it will be evident to a person skilled in mechanics that a single set of grooves and points placed in the two bracket-sections will suffice for purposes of adjustment.

Each bracket-section is provided with a slot 3C, through which passes a screw 7 or equivalent means of connecting and clamping the parts together, and in one of said sections I prefer to form a rectangular groove or seat 8 (see Figs. 5 and S) for the reception of the nut 7n of said screw 7.

The outer ends of the curtain-sections 3b are each provided with duplicate journalbearings 9 and 9, whereby the brackets are rendered reversible, or, in other words, the bracket may be used either on the right or left side of the frame at will, and thus accommodate either a right or left hand springroller.

The construction of the bracket being substantially of the character hereinbefore specified, the length of the bracket may be adjusted to any given depth of framing by slipping the sections 3a and 3b longitudinally on each other, and at the same time any inequality ot' the height of the shoesl (or in case the framing A has sunken at one side) may be provided for by canting the curtain-section either up or down until the points 6 enter the proper grooves 5, after which the nut and screw 7 7a or other suitable clamp may be tightened to secure the sections 3 3b in the desired position.

Having thus described my invention, what I claim, and desire to secure by Letters Pat ent, is-

l. In a curtain-bracket, the combination of two lapping longitudinally-adj ustable armsections having adjacent corrugated interlocking surfaces which permit said arm-sections to be adjusted longitudinally in a right line and also at an angle to each other and a clamp for securing the parts when adj usted in either position, substantially as and for the purposes specified.

2. The combination, in a curtain-bracket, of two bracket-sections adjustable one on the other, one of said sections provided with longitudinal grooves and one with points or proj ections adjacent to one end thereof, whereby said sections may be adjusted in a right line or at an angle to each other, substantially as and for the purposes speciied.

3. The combination, in a curtain-bracket, of two adjustable sections, each provided on its inner or contacting face with grooves and points, whereby said sections may be adj usted to a right line or at an angle to each other, substantially as and for the purposes specified.

4. In a curtain-bracket, the combination of two longitudinally-slotted extensible arm-sections having adjacent corrugated interlocking surfaces and means for pivotally and adjustably connecting and clamping said armsections, substantially as and for the purposes specified.

In testimony whereof I afx my signature, in presence of two witnesses, this 26th day of .Ianuary, 189;".
